The threshold potential for the classical depolarization-activated transient outward K+ current and Cl- current is positive to -30 mV. With the whole cell patch technique, a transient outward current was elicited in the presence of 5 mM 4-aminopyridine (4-AP) and

We compared intracellular K+ and Na+ ion concentrations during cell growth and differentiation of a mouse myeloid leukemia M1 cell line. Cells undergoing mitosis had higher K+ concentrations than quiescent cells. Treatment with a K+ channel blocker and furosemide enhanced

Nonadiabatic photodynamical simulations of 4-aminopyrimidine (4-APy) used as a model for adenine were performed by embedding it between two stacking methyl-guanine (mGua) molecules to determine the effect of spatial restrictions on the ultrafast photodeactivation mechanism of this nucleobase. A hybrid

Ab initio calculations on the HF-SCF 6-31g* level were performed on tautomers as well as protonated and deprotonated species of thiamin. Aspects of the proton relay function of the 4'-aminopyrimidine ring in the thiamin catalysis were studied on model systems.
Potential roles of the aminopyrimidine ring in thiamin catalyzed reactions.
